Abstract

FIELD: oil and gas production. SUBSTANCE: invention is aimed at increasing oil recovery of bed, decreasing corrosion activity of recovered product, and preventing increased stability of water-oil emulsion. Into the bed, before initiation of burning, solution containing 29- 30% of ammonium sulfate is pumped in through injection well. Then burning is initiated and oxidant, e. g. oxygen is pumped in followed by other operations associated with maintaining interbed combustion. EFFECT: increased oil recovery and reduced corrosion of equipment.

Изобретение относится к нефтедобывающей промышленности, в частности к способам разработки залежи нефти с применением тепловых методов. Целью предлагаемого изобретения является повышение нефтеотдачи пласта, понижение коррозионной активности добываемой продукции и предотвращение повышения стабильности водонефтяной эмульсии. Способ осуществляется в следующей последовательности: в пласт до инициирования горения через нагнетательную скважину закачивают раствор, содержащий 29-30% углекислого аммония. После закачки раствора переходят к инициированию горения и закачке окислителя, например, воздуха, затем переходят к другим операциям по применению способа внутрипластового горения. Изобретение позволяет увеличить нефтеотдачу, понизить скорость коррозии оборудования, предотвратить образование водонефтяной эмульсии повышенной стабильности.The invention relates to the oil industry, in particular to methods for developing oil deposits using thermal methods. The aim of the invention is to increase oil recovery, lowering the corrosion activity of the produced products and preventing increasing the stability of the oil-water emulsion. The method is carried out in the following sequence: before the initiation of combustion, a solution containing 29-30% ammonium carbonate is pumped into the formation through the injection well. After the injection of the solution, they proceed to initiating combustion and injecting the oxidizing agent, for example, air, then proceed to other operations on the application of the in-situ combustion method. The invention allows to increase oil recovery, reduce the corrosion rate of equipment, prevent the formation of water-oil emulsions of increased stability.
